Abstract
Dans un aspect de la présente invention, un équipement de respiration auxiliaire comprend un ensemble de régénération d'atmosphère en circuit semi-fermé, relié par un ou plusieurs tuyaux à un clapet d'arrêt automatique et à une interface casque ou masque, ledit ensemble au repos pendant les opérations normales de plongée étant maintenu à une pression excédant la pression externe ambiante. Un autre aspect de l'invention concerne un ensemble de régénération d'atmosphère en circuit semi-fermé pour équipement de respiration auxiliaire, l'ensemble se fixant par un ou plusieurs (2) tuyaux sur un clapet d'arrêt automatique (4) et une interface casque ou masque (17), et comportant au moins un poumon auxiliaire (1), un absorbeur d'humidité (10), un laveur de gaz carbonique (11), et un limiteur (6) se fixant sur une bouteille de gaz pressurisée (5) de sorte que lorsque l'ensemble est actionné, le gaz peut s'y écouler à une vitesse sensiblement constante. L'avantage d'un tel ensemble est qu'il peut être maintenu, au repos, à une pression excédant la pression externe ambiante. Le maintien d'une surpression dans l'ensemble de régénération en service évite le risque d'infiltration d'eau de mer dans ce dernier.In one aspect of the present invention, an auxiliary breathing equipment comprises a semi-closed circuit atmosphere regeneration assembly, connected by one or more hoses to an automatic shut-off valve and to a helmet or mask interface, said assembly at rest during normal diving operations being maintained at a pressure exceeding the ambient external pressure. Another aspect of the invention relates to an atmosphere regeneration assembly in a semi-closed circuit for auxiliary breathing equipment, the assembly being fixed by one or more (2) pipes to an automatic shut-off valve (4) and a helmet or mask interface (17), and comprising at least one auxiliary lung (1), a moisture absorber (10), a carbon dioxide washer (11), and a limiter (6) which are fixed on a bottle of pressurized gas (5) so that when the assembly is actuated, the gas can flow therein at a substantially constant speed. The advantage of such an assembly is that it can be maintained, at rest, at a pressure exceeding the ambient external pressure. Maintaining an overpressure in the regeneration unit in service avoids the risk of seawater infiltration into the latter.
